John Goreham Contributing Writer, GM-Trucks.com 5-15-2019 General Motors has earned the "Automotive Excellence Award" for its innovations on the new generation Silverado. The award was presented to GM by The Steel Market Development Institute (SMDI). The GM Silverado design earned the award for its innovative use of advanced high-strength steel. The all-new 2019 Chevrolet Silverado has a body structure composed of nearly 86 percent steel. That includes ultra-high-strength steel (UHSS), advanced high-strength steel (AHSS) and high strength low alloy (HSLA) materials in the Silverado's cab, bed, and frame. The use of these strong, but lightweight materials contributed to the new Silverado's mass reduction. During the all-new Silverado's launch presentation, GM President Mark Reuss told the audience that the head of a hammer is steel. He added, “I don’t know how much work you’d get done with an aluminum hammer.” Related Story: 2019 Silverado Focus – Fuel Saving Technology - Facts, Specs, Images "Automotive Excellence Award winners use advanced high-strength steel in applications to provide the best value for OEMs and consumers while also improving vehicle performance and sustainability," said Jody Hall, vice president of the automotive market at SMDI. "With automakers shifting their vehicle mix to favor trucks, CUVs and SUVs, new steel grades are leading the way in innovation. The 2019 Silverado is a great example of the capability of these next generation steel grades." The new 2019 Silverado is 450 pounds lighter than the outgoing truck (crew cab V8 models). High strength steel makes the frame stronger, and stiffer, and also lighter. The cargo bed is also a new lighter, stronger steel.

I have a 2015 ltz z71 premium crew cab 1500 and was wandering if changing my lower control arms from the stock aluminum to the cast steel will affect the truck at all. Or if the two control arms are interchangeable below is the pic of what the control arms look like after I changed them out. Still have to add the washer but looks like they will work? Everything fits correctly other than the balljoint bolt length

John Goreham Contributing Writer, GM-Trucks.com 9-12-2018 Let's face it. The Bison is a Colorado ZR2 with skidplates, better bumpers, and the cool snorkel. Except you can get the snorkel just as easily on a ZR2 or even a base Colorado. Chevy isn't supplying them from the factory. To have that cool appendage, you have to install it yourself or have someone do it for you. Cutting out the catcher's mitt-sized hole in the fender is one thing, you can always replace a fender, but drilling into the A-Pillar may seem scary. That A-Pillar is responsible for a lot of safety functions as well as being a tougher part to repair if need be than a removable fender. To drill or not to drill, that is the question. It is also a question we put to the Facebook Chevy Colorado ZR2 club. 77 of the 144 respondents said "No F'ing Way!" to drilling into that particularly sensitive spot. To see if the A-Pillar is off limits, we reached out to the Steel Market Development Institute (SMDI). These are the folks who help automakers to develop the exotic steels now used for lightweighting and strengthening key parts of trucks and cars. First, we asked SMDI what exactly the A-Pillar in a Chevy Colorado is made from and how it is made. They told us, "A-pillars are typically designed with 3 layers of sheet metal. An outer body side panel which is the painted exterior surface, and an outer (middle layer) and inner (interior to the passenger compartment) A-pillar structures. The outer panel is made of mild steel and is mostly to cover the structure of the vehicle and contribute to styling. The two structural pieces for the A-pillar are made of ultra-high-strength steel (UHSS) and have tensile strengths greater than 1000 MPa. The outer is a press-hardened steel (PHS), also called a hot-stamped steel. The inner is a multi-phase grade (stamped at room temperature). These grades are 4-6 times stronger than the mild steel of the outer panel and deliver exceptional performance in strength and resistance to intrusion (bending or crush in a collision). These grades also deliver efficient designs of the A-pillar in that higher strength allows for a thinner section design (over lower strength materials such as aluminum) which gives better visibility to the driver." SMDI reviewed the video of the install from AEV, the supplier of the snorkel. We then asked them if they thought the drilling was any kind of concern. SMDI replied, "The way this process is shown in the video is more than adequate to attach the snorkel without compromising the performance integrity of the A-pillar. It is attached directly to the outer panel and does not disturb the load path performance provided by the outer and inner structural pieces." So the experts say "full send!" Send us images and video if you do an install of your own. We'd love to do a post showing them off. Here's how to get the snorkel kit.

Visitors to Chevrolet.com are prompted to watch these three videos, which all seem to make the same point. You've got to be an idiot to buy a truck with an aluminum body. That said, each video goes about it in very unique way. Take a look: https://www.youtube.com/watch?v=vIC7Fw1rFF4 So, what do you think? Is highlighting a short term difference a good long term move for Silverado marketing?
